First, what is arrogance?
The prophet (S.A.W.) defined it for us in an authentic hadith reported by Imams Muslim and At-Tirmithi, "One will not enter Paradise, if one has an atom’s weight of arrogance in his/her heart." a man then asked, "One may love his clothes to look good and his shoes to look good?!" The prophet replied, "Allah is beautiful and loves beauty, arrogance is: rejecting the truth and looking down on people."
The different degrees and types of arrogance: The most evil kind of arrogance is rejection of the truth and not following it. In this context, many verses were revealed to scold arrogance and the arrogant people. Examples are: On the Day of Judgment, it is said to the arrogant people in surat Ghafer, (Verse 76), what can be translated as, "Enter the gates of
Hell to abide therein, and (indeed) what an evil abode of the arrogant!"
